application overview demonstrates the use of X-ray diffraction (XRD) barite
grinding plant for sale in six mining case studies: phase identification of
lithium and manganese ores; quantification of heavy mineral sands;
quantification of phases in iron ore; quantification of quartz in talc, and
quantification and cluster analysis of bauxites.Valuable information is obtained
using state-of-the-art PANalytical technology, including high-speed detectors
and advanced software, which illustrates the potential of XRD as a high
throughput process control solution.XRD is a versatile, non-destructive
analytical tool that is widely used throughout the mining industry. It is long
established as an important method for the identification of phases in raw
materials, for process control during ore beneficiation, and for the quality
control of final mineral products. The recent introduction of PANalytical’s
X’Celerator, and the subsequent PIXcel, detector has revolutionized X-ray
analysis, further extending its possible applications in the mining industry.In
addition to innovations in hardware, PANalytical has developed sophisticated
software that enables even inexperienced laboratory personnel to conduct
automatic data analysis and reporting. quarry
equipment manufacturer PANalytical’s XRD software utilizes important tools
such as standardless Rietveld and cluster analysis for large data sets, helping
the mining industry to mine with greater efficiency than ever before.Phase
Identification of Lithium and Manganese OresXRD is the primary analytical
technique for identifying the phases present in ore samples, as well as
understanding the results of beneficiation procedures. In this case study, XRD
analysis of raw lithium ore (figure 1) was used to identify the phases spodumen,
feldspar (K-feldspar and Na-feldspar), quartz and muscovite. The manganese ore
showed the presence of braunite, bixbyite and a number of minor phases (figure
2). This type of analysis benefits greatly from a highresolution diffraction
pattern, as the patterns for these major phases show severe overlapping.Figure

relevant impurities.Quantification of Heavy Mineral SandsThe X’Celerator
detector makes it possible to analyze heavy mineral sands in a scan time of less
than five minutes, providing data of suitably high quality for Rietveld
analysis. Co radiation was used for this case study as it is ideal for
iron-bearing materials such as heavy mineral sands.Rietveld methodThe analysis
of ores and minerals with the standardless Rietveld method has several
advantages. You can distinguish between and determine all existing phases in
just a few minutes. Crucial process parameters can be calculated directly from
the phase quantification. Line overlaps, sample height and preferred orientation
do not influence the results. For this method a fast detector is recommended to
measure and evaluate a whole diffractogram in minutes. No standards or
calibration are needed.
